Plant Nutriton: Sherlock Holmes Style

For those curious about the question "why are some nutrient mobile and others immobile in the plant?" there are several additional reasons but a big one is that some nutrients are used as an integral part of cell structure and so once they have been used they are bound up tight, while other nutrients are used in helper chemicals that stay dissolved for use in various processes so they are not bound as part of a structural cell.

Always wondered that thank you.

[@oftenwrongphong]

Thanks. Now I know.

Also, these mobile elements sort of act as if they were dissolved in water. They will spread out throughout the container so that the concentration is pretty consistent. It works similarly within the plant. Since the elements can move around they will form some type of equilibrium. If a plant has too little of X then it will show up on old growth more because more if that growth exists which requires more of the nutrients but which the concentration is low across the entire plant. Old growth is more "functional" in that it is structure that is working at it's capacity to function as a leaf should. New growth though mainly exists to grow and so the nutrients are not as critical since much of the photosynthesis machinery is being created rather than used(although nutrients used for cell division are necessary and such deficiencies will show up in new growth which is usually deformities, slow growth, etc). A plant one large chemical equation(same is true of all living things) and so having the equation function as it is suppose to is what is required.

@@jsmdnq In the soil and in the plant nutrient mobility have some differences, just so no one goes away with the wrong impression. A nutrient can be fairly immobile in soil yet mobile in the plant or vice versa.

@Phil Philup Your *shoddy* insult is typical of people who think they know more than they really do. Mg has many jobs in a plant, which is why it is partially relocatable. Mg is integrated into some cellular structures where it is immobilized,(Wood and straw ashes contain substantial Mg) but Mg is also central to many enzymatic processes in the chloroplast as well as being central to the function of the chlorophyll a and b molecules. (eg. RuBP carboxylase and in other stromal enzymes involved in CO2 accumulation.) It is not firmly bound to a cell in these roles and so partially recoverable for transport.

Sepp Holzer says that if you feed plants and water them, they dont gorw long roots, if they lack food and water their root systems will grow bigger, they will search for food at a greater distance from the trunk.

AWESOME!

Awesome, thanks 😊

[@mytech6779]

The chart with nutrient availability with pH. I hate it when people don't clarify if the data is for *soil* availability or the ability of a plant to take the nutrient from solution. They are totally different things, the problem of solubility, and nutrient dynamics generally, in mineral soils are not at all relevant to pre-dissolved nutrient solutions used in a greenhouse on generally inert media.

Do you see chlorine or fluorine from tap water damage on plants?

[@rosemacaskie]

I read that humic and fulvic acids, they think, help with the the mobility of food in the plant I that knowing how food enters cells in living organism is cutting edge science. I don't know how study of this aspect of humic acids is seen now. Of course humic and fulvic acids help make nutrients avaiable to plants in the soil. I suppose they are capable of separating nitrogen that has got attracted to colloidial particle from the particle, so that the nutrient becomes dissolved in the soil water but that is my guess.

[@kylesyx8432]

I know this is an old comment. Hum.and fulvic acids ..."chelate" metallic ions. Making nutrients water transferable when Ph is good (5.8 - 6.2 ) micro/fungi love fulvic,& hum.acid is like a bio stimulant, and nutrition for mycorrhizae

[@davidbryden7904]

I've read the same, and some evidence that CalMag uptake is aided by humics.

[@nicoleyoung3927]

My plant is blocking out nitrogen it has zero nitrogen in it from a nutritional lock out from one feed, the first time I said it it started to die! Can I save it by transplanting it? It’s 14 feet tall

[@kylesyx8432]

Zero Nitrogen, ? how do you know this? You know nit. Is not available ? Can you check your Ec.,ppms Or your P.h.? Id leach, soil w just clean water, add some (natural nit.)Worm castings, plants us nit. In everything they do.(add a little lime.)Calcium is your building blocks for plant growth. And lastly a Good balanaced (chelated) water soluble nutrient w/ multible soarses of N.( nitrate,urea, &,ammonical N). @ about half strength. Your micro./fungi life may be suffering too. W.Castings w help get life jump started again. If all that doesnt erradicate the problem. May not be salvagable. (Diseases kills quick) good luck. Hope that helps. When plants have been potted for long periods of time. And soil is depleted, this tipically fixs my issues.

13:57 again thats nitrogen toxicity, phosphor makes a hue change, the leaves don't darken they change colour, lighten slightly, interveinal chlorosis and the veins look dark The more the plant is feeding on mobile nutrients and the more works it puts into things the redder or purpler those main stems and leaf stems go, nitrogen doesn't really hurt that much things yellow and fall off, phosphor is more static of a nutrient, its not very mobile at all, the plant looks like it hurts all over, purpling, hue change to all but your very tops, it appears to darken but its the leaves taking a blue hue to things..

Can I reuse the runoff water again how many time is ok

[@mytech6779]

It would be best to collect it in a large enough tank that having it tested for nutrients would be a reasonable cost. It would also be best to mix it with some fresh water, with a test you could use up to half as you can calculate how to adjust additional nutrients needed to return balance. Without a nutrient test I would limit to about 10% of water and reduce new fertilizer added to water about 5-10%. 10% should be worthwhile as you shouldn't normally have more than about 20% runoff in an effective operation.

7:06 are you sure thats a genetic mutation.. look again, clear your perspective for a moment, one thing i noticed with cannabis is nitrates do a hell of a lot towards mutations. You see dark green leaves, bright thick veins to the plant, but the real visible white veins on fans is a first clue things could get weird. You end up with one side of the leaf growing in a bit retarded, it wasn't fed the right proteins, or it was staved but one side of the leaf can just develop wrong, and it tends to come from the veins Chase them and you can see the twist, or the vein will be zigzagging, there isn't the usualy symmetry that you would expect. Like I say I see it in weed all the time, variegation, TMV, its all different sides to the same coin, if the mutation happens in the vein you get a weird leaf, if it happens in a node then the mistake propagates to the rest of the plant, if its in the point where the leaves meet up you might see some wonkyness. But dark green leaves and bright white veins follow mutations around like a curse. If it isn't a cause it sure as shit is an effect. Excuse my language DNA at its most basic level is a sugar backbone, with a bit of phosphate and the CTAG part that is all coded with nitrates, mutations are errors in the coding the plant couldn't correct. It could be genetic. But it could also just be a mis alignment in the structure, if the plant was being fed the wrong proteins when it was being built then it gets built wrong, and DNA builds everything, cells, proteins, its literally the whole game, sugar retention for cell growth. Too much nitrogen and your plant will code things in error, it can't help it, the nitrates are rare in nature, she snaps them up before anything else does or before they wash out of the plants reach, if you are pushing hard enough with the light she sweats that wasted energy out of the leaf, making it burn, if not then its gonna be burning off the nitrogen as much as it can, making the leaves darken to burn it off more and more. I can get the white veins to be real shown in weed by adding too much green in my 3 part, its repeatable and easy, but the mutations themselves are random, something or nothing might happen past the leaves getting dark and those veins really standing out and growing weird, depends what the genetics wants to do, it's like poking the hulk to make him angry lol

[@silentday4503]

The ‘OCD’ thing gets thrown around any time others do things differently than us. True obsessions/compulsions (the only ones that warrant an association with the acronym), are pathological and are indicative of a severe mental illness with a spiritual root. The more we misuse words, the more they lose their meaning.
